'SHIFTING-BAR FOR SLEIGHS.

SPECIFICATION forming part of Letters Patent No. 360,997, dated April12, 1887.

Application filed October 11, 1886. Serial No. 215,844. (No model.) i

.To all whom it may concern.-

Be it known that I, WELLs M. PEoK, of Syracuse, in the, county ofOnondaga, in the State of New York, have invented new and usefulImprovements in Shifting-Bars,of which the following, taken inconnection with the tating the employment of a wrench or other tool toaccomplish the desired result.

To this end, then, the invention consists in providing a cross-barsecured to the runners and recessing the same upon its under side forthe reception of the movable metallic bar, either half-round or oval,said bar being seated in the recess and carrying the couplingshacklesand securing the same at any desired adjustment or shift by means ofclips and thumb-screws, all as hereinafter more specifically described,and pointed out in the claims.

In specifying my invention, reference is had to the accompanyingdrawings, in which like letters indicate corresponding parts in all theviews.

Figure 1 is a side elevation showing the device in position secured tothe runners of a cutter or sleigh, the bar being adjusted centrally.Fig. 2 shows-the same view with the shifting-bar adjusted to one side.Fig. Sis an inverted bottom plan showing the arrangement of the clipsand clamping devices. Fig. 4 is an enlarged detail, partly in section,showing the contour of the recess in the cross-bar, also that of theshifting-bar. Fig. 5 is an enlarged section of the crossbar andshiftingbar, showing the clamp-screw passing through the clamping-plateand bearing against the shifting-bar.

A represents the crossbar, which," for the purposes of elegance inconstruction, I construct, preferably, of hard wood. The same may bevery light and tasty in design.

The under side of the bar A is provided with a semicircular recess, a,extending throughout its length, Figs. 3, 4, and 5. In this longitudinalrecess I place the shifting-bar proper, B, which is made ofhalf-round oroval metal, preferably iron or steel, said bar B fitting snugly into therecess, so that its straight surface comes flush with the straight edgeof the bar A. The coupling-shackles FF are welded onto the bar B, orcast integral therewith, so as to form one piece, and, as will beobserved upon reference to the drawings, the said bar B slideslongitudinally in the recess or seat a of the crossbar A.

To secure the bar B in its recess, I provide clips E E, applied to thebar A, as best shown at Fig. 4. The clip E is applied to the crossbar Aat one end thereof, as shown at Fig. 2, and E at the point on thecrossbar A where the inner shaft coupling comes when the bar B isshifted to one side.

7 To secure the bar B firmly in position when adjusted, I provideclamping devices D O.

0 consists of a plate of metal,passing through the clip bar and drilledand threaded for the reception of the clamp-screw D, which passesthrough 0 and bears against the bar B, as shown in Fig. 5.

It will be observed that the clips E E connect the cross-bar A andplates 0 O, and that the sliding bar is located in the groove to and isheld therein by the plates 0 0.

Additional clips, H, may be applied to the cross-bar A to preventsplitting in case the device is made very light for extra-light work.

The operation of my invention will be readily understood upon referenceto the drawings and a consideration of the foregoing. The

shifting-bar being centrally adjusted, as shown in Fig. 1, and it beingdesired to shift thesame to one side, it is simply necessary to releasethe clamping-screws D D, shifting the bar B over to the desiredposition, and setting up the clamp-screws D D.

The device is compact and much neater than the tubular shifting-bars andthe bars heretofore employed,and it is adaptedfor light work, as well asto the heavier types of cutters and sleighs.

I am aware that shifting devices for cuttershafts having a sliding barlocated in a grooved cross-bar and a spring-catch for locking the 5 thegroove or recess in the cross-bar, where it is supported on the plates0, and the advantage consists in the readiness with which it can beadjusted to any desired point by simply releasing the screws D D andsliding the bar IO over, then setting up the screws, beside which thedevice is much stronger and more durable and may be made much lighterthan the prior devices for this purpose.

Having fully thus described my invention,

15 what Ielaim as new, and desire to secure by I Letters Patent, is

In the herein-described shifting device for cutter-shafts, thecombination of the cross-bar A, having the longitudinal groove (1, andthe bar B, sliding in said groove a, the clips E E, connecting thecross-bar A and the plates 0 C, the plates 0, bearing against thesliding bar B, and the adjusting-screw D, passing through the plate andbearing against the bar B, all substantially as and for the purpose setforth. In testimony whereof I have hereunto signed my name, in thepresence of two attesting witnesses, at Syracuse, in the countyofOnondaga, in the State of New York, this 8th day of Octoher, 1886.
